7c16caa336 Changes For Bug 352 
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM

834105502d Do not mark ALL terminators live if any instruciton in the block is live. We only 
want to mark it live if it is an unconditional branch.  This fixes bug:
ADCE/2002-05-28-Crash.ll and makes this pass _much_ more useful.

dc62f1e021 Fix bug: ADCE/2003-06-11-InvalidCFG.ll 
This was because we were deleting large chunks of functions without an exit block, because the post-dominance
information was not useful.  This broke crafty and twolf.

bf3a099a62 Updates to work with recent Statistic's changes: 
* Renamed StatisticReporter.h/cpp to Statistic.h/cpp
    * Broke constructor to take two const char * arguments instead of one, so
      that indendation can be taken care of automatically.
    * Sort the list by pass name when printing
    * Make sure to print all statistics as a group, instead of randomly when
      the statistics dtors are called.
    * Updated ProgrammersManual with new semantics.

33fca976ee * Fix bug: test/Regression/Transforms/ADCE/2002-07-17-AssertionFailure.ll 
which was caused by us not running the "drop references of dead
  instructions" code when there were no basic blocks that were dead.

  We still don't want to do some of the stuff we do if there are dead
  basic blocks, but we DO want to drop references of dead instructions,
  so we factor the common code out to a new method.

2675007573 * Standardize how analysis results/passes as printed with the print() virtual 
methods
* Eliminate AnalysisID:  Now it is just a typedef for const PassInfo*
* Simplify how AnalysisID's are initialized
* Eliminate Analysis/Writer.cpp/.h: incorporate printing functionality into
  the analyses themselves.
